CriticalSignal strong$26,500 estimated replacement

What happened: Supply temperature and runtime are both rising at the same time. The unit is running longer and still delivering warmer air.
Why Rivet thinks so: Two independent measurements moved together, which distinguishes a capacity fault from a setpoint or occupancy change — a thermostat change would lower runtime, not raise it. This unit also has 3 recorded repairs, including prior refrigerant loss with no leak located.
Why it matters: Declining cooling capacity typically ends in compressor failure. Coverage may still apply, so the order of operations matters: verify before authorizing paid work.

What to do next

Request a diagnostic call — Ask the vendor for a full leak search and verification of refrigerant charge and compressor performance.

CriticalSignal strong

What happened: Reading has moved up 8.4 from a typical 11.5, and has stayed outside its normal range for 6 consecutive readings.
Why Rivet thinks so: Readings are 11.79 standard deviations from this unit's established baseline of 11.5 (typical variation ±0.7), and the deviation held across 6 consecutive readings rather than appearing as a single spike.
Why it matters: Sustained deviation in daily runtime usually precedes a service call. Catching it now is the difference between a scheduled inspection and an emergency response.

What to do next

Schedule an inspection — Have the unit assessed before the next scheduled service interval.

What happened: Reading has moved up 7.7 from a typical 70.6, and has stayed outside its normal range for 5 consecutive readings.
Why Rivet thinks so: Readings are 10.18 standard deviations from this unit's established baseline of 70.6 (typical variation ±0.8), and the deviation held across 5 consecutive readings rather than appearing as a single spike.
Why it matters: Sustained deviation in supply temperature usually precedes a service call. Catching it now is the difference between a scheduled inspection and an emergency response.
